Individual certified emeralds, sold in USDT. A sale can transfer ownership while the stone stays vaulted, or it can send the stone to the buyer. The second kind shrinks the reserve — so the system refuses it whenever the stone is still needed to back what has already been promised.
Two settlement modes, and the difference between them is the whole point.
Ownership of the stone changes; the stone does not move. It stays in custody, keeps counting towards the reserve, and the issuance ceiling is untouched.
Always available. Settles as soon as both sides are ready.
The stone leaves the vault and travels to the buyer. The reserve shrinks by its carat weight and the ceiling falls accordingly.
Available only while the reduced ceiling still covers every outstanding entitlement and every token issued — checked when the offer is accepted and again at settlement.
The buyer's USDT is held by the market contract, not by the seller. For a physical sale it is released when the buyer confirms receipt — not when the parcel is handed to a courier.
If delivery fails, the funds go back.
The custodian releases and hands over. The carrier records movement. The buyer confirms arrival, and only the buyer can do that.
Every handover is an event on the chain, signed by whoever performed it.
Prices are asking prices in USDT. The delivery column shows whether this particular stone could physically leave the vault right now.

Every stone that has left the vault, and where it is. Each checkpoint was signed by the party that recorded it; none of them can be edited afterwards.
